Abstract
Description
Technical Field
[0001] This utility model relates to the field of tea roasting technology, and in particular to a tea roasting device that facilitates waste heat recovery. Background Technology
[0002] Tea processing, also known as "tea making," is the process of turning fresh tea leaves into various semi-finished or finished tea products through a series of processing steps. During the tea processing, the leaves need to be roasted to dry them and create unique quality characteristics.
[0003] In existing technologies, most tea roasting boxes have a heating element installed inside. The tea leaves are then piled up inside the box, and the heating element heats the tea leaves to roast them. However, because there is no turning mechanism inside the box, the tea leaves cannot be moved during the roasting process, resulting in poor heating of the piled-up tea leaves and a long roasting time.
[0004] To address this issue, a tea roasting device that facilitates waste heat recovery is proposed. Utility Model Content
[0005] The purpose of this invention is to solve the problems existing in the prior art.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a tea roasting device for easy waste heat recovery, comprising: a roasting box, a ventilation plate fixedly installed at the bottom of the inner cavity of the roasting box, an opening and closing door connected to one side of the roasting box via a hinge, a heating component disposed at the bottom of the inner cavity of the roasting box below the ventilation plate, a uniform shaking component disposed inside the roasting box, a plurality of fixed components disposed at one end of the surface of the uniform shaking component, a plurality of arc-shaped ventilation cylinders movably connected to the surfaces of the plurality of uniform shaking components, and a waste heat extraction component disposed at the top of the roasting box.
[0007] Furthermore, a temperature sensor is fixedly installed on the inner wall of the bottom of the baking oven cavity, on the side above the ventilation plate; a U-shaped fixing plate is fixedly installed on one side of the outer wall of the baking oven; an observation window is fixedly embedded in the surface of the opening and closing door; a control terminal is fixedly installed on one side of the observation window; a handle is fixedly installed on one side of the opening and closing door, below the control terminal; and pressure relief holes are provided on both sides of the top of the baking oven.
[0008] Furthermore, the heating assembly includes a mounting frame and a blower. The two ends of the mounting frame are fixedly installed on both sides of the inner cavity of the baking oven. Heating resistance wires are fixedly installed on the surface of the mounting frame. The blower is fixedly installed on the bottom of the other side surface of the outer wall of the baking oven through a mounting base. The output end of the blower is embedded in the side wall of the baking oven through a connecting pipe and extends below the mounting frame.
[0009] Furthermore, the uniform shaking assembly includes a motor, two U-shaped sliding columns, and multiple transmission rods. The motor is fixedly installed on one side of the U-shaped fixed plate. The output end of the motor passes through the surface of the U-shaped fixed plate via a bearing and is fixedly installed with a half-gear. The two ends of the two U-shaped sliding columns are fixedly installed at the upper and lower ends of the outer wall of one side of the baking oven. A spiral-shaped sliding plate is movably fitted on the surface of the two U-shaped sliding columns. A first toothed plate is fixedly installed on one side of the spiral-shaped sliding plate, and second toothed plates are fixedly installed on both sides of the inner wall of the spiral-shaped sliding plate. The half-gear is rotated and interlocks with the two second toothed plates.
[0010] Furthermore, one end of each of the multiple transmission rods is embedded in the other side of the inner wall of the baking oven via bearings, and the other end of each of the multiple transmission rods is embedded in one side of the baking oven via sealed bearings and fixedly fitted with driven gears. The surfaces of the multiple driven gears are meshed with the first gear plate. Support plates are fixedly fitted at both ends of the surfaces of the multiple transmission rods. T-shaped grooves are formed through the bottom ends of the opposite inner surfaces of the multiple support plates. First limiting grooves are formed above the inner cavities of the multiple T-shaped grooves near the ends. Second limiting grooves are formed through the inner sides of the multiple first limiting grooves.
[0011] Furthermore, the fixing component includes a sliding post, the surface of which is movably embedded inside the first limiting groove, a toggle rod fixedly connected to one side of the sliding post, the surface of which extends through the interior of the second limiting groove, a spring fixedly connected to the top of the sliding post, one end of which is fixedly connected to the top of the inner cavity of the first limiting groove, and an insert post fixedly connected to the bottom of the sliding post.
[0012] Furthermore, T-shaped sliding plates are fixedly connected to the top of both sides of the arc-shaped ventilation duct, and fixing holes are opened near the ends of the top surfaces of the two T-shaped sliding plates. One end of the insertion post moves through the bottom of the first limiting groove and extends into the corresponding fixing hole. Handles are fixedly connected to both ends of the arc-shaped surface of the arc-shaped ventilation duct.
[0013] Furthermore, the waste heat extraction assembly includes an exhaust fan fixedly mounted on the back surface of the baking oven via a mounting base. The input end of the exhaust fan is embedded through a connecting pipe through the top of the baking oven and is fitted with a trapezoidal cover. The output end of the exhaust fan is embedded through a connecting pipe through the bottom of the back of the baking oven and is fitted with an air supply hood. The air supply hood is located above the ventilation plate.
[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0015] 1. In this utility model, by moving the lever upward, the lever causes the sliding column to move upward and compress the spring. At the same time, the insert follows the sliding column upward and disengages from the inside of the fixing hole, releasing the restriction on the T-shaped sliding plate. By using the same method to release the inserts inserted at both ends of multiple arc-shaped ventilation cylinders, the arc-shaped ventilation cylinders can be pulled out by the handle. Then, an appropriate amount of tea to be roasted is placed inside the multiple arc-shaped ventilation cylinders. Then, the lever is moved again to insert the T-shaped sliding plate into the corresponding T-shaped groove. By releasing the lever, the spring returns to its original position, causing the insert to re-insert into the fixing hole and fix the arc-shaped ventilation cylinder, making it easy to put in and take out the arc-shaped ventilation cylinder.
[0016] 2. In this invention, a heating resistance wire is energized to heat its surroundings. A blower blows hot air around the heating resistance wire, which rises through a ventilation plate and passes through ventilation holes on the surface of an arc-shaped ventilation cylinder to heat, bake, and dry the tea leaves. Meanwhile, a motor drives a half-gear to rotate, which meshes with the second gear plates on both sides, causing the U-shaped sliding plate to move back and forth on the surface of the U-shaped sliding column. This, in turn, drives multiple driven gears meshing with the first gear plate to rotate synchronously. Simultaneously, the driven gears drive the transmission rod to rotate back and forth in an arc shape, causing the multiple arc-shaped ventilation cylinders to sway. This causes the tea leaves inside the arc-shaped ventilation cylinders to tumble and roll back and forth. The hot air moves upward from below, passing through the surface of the arc-shaped ventilation cylinders to contact and dry the rolling tea leaves, resulting in more even heating and improved baking effect.
[0017] 3. In this utility model, the upward-moving residual heat will pre-accumulate at the top of the inner cavity of the baking oven and gradually be discharged through the pressure relief hole. At this time, due to the operation of the exhaust fan, some of the residual heat is extracted by the exhaust fan through the trapezoidal cover and sent back to the bottom of the inner cavity of the baking oven through the air supply cover, and then moves upward again to bake and dry the tea leaves inside the arc-shaped ventilation duct. The residual heat extraction component facilitates the extraction and reuse of most of the discharged residual heat, reducing heat loss and energy consumption. Attached Figure Description

[0035] In one embodiment, the uniform shaking component 4 includes a motor 401, two U-shaped sliding columns 402, and multiple transmission rods 403.

[0045] Specifically, such as Figure 2-3 As shown: The exhaust fan 701 extracts and recycles some of the residual heat flowing to the top of the inner cavity of the baking oven 1 through the trapezoidal cover 701. The trapezoidal cover 701 facilitates the expansion of the residual heat extraction effect.
[0046] Working principle:
[0047] This tea roasting device can be connected to an external power source to provide power to its internal components.
[0048] When roasting tea leaves, open the opening door 2, then move the lever 502 upwards. The lever 502 moves the sliding column 501 upwards and compresses the spring 503. At the same time, the insert 504 moves upwards with the sliding column 501, disengaging from the fixing hole 603 and releasing the T-shaped slide plate 601. Repeat this process to release the inserts 504 at both ends of the multiple arc-shaped ventilation cylinders 6. The arc-shaped ventilation cylinders 6 can then be pulled out using the handle 602. Place an appropriate amount of tea leaves to be roasted into the multiple arc-shaped ventilation cylinders 6. Then, move the lever 502 again to insert the T-shaped slide plate 601 into the corresponding T-shaped groove 410. Release the lever 502. Spring 503 resets and drives the insert 504 to re-insert into the fixing hole 603 to fix the arc-shaped ventilation tube 6. Then, the opening and closing door 2 is closed, and the temperature sensor 102, heating resistance wire 302, motor 401 and exhaust fan 701 are started through the control terminal 202. The appropriate temperature range is preset through the control terminal 202, and the temperature inside the baking oven 1 is detected in real time through the temperature sensor 102. When the detected temperature is lower than the preset temperature range, the control terminal 202 will continue to run the heating resistance wire 302 and the blower 303 to send hot air into the baking oven 1. When the detected temperature is higher than the preset temperature range, it will stop to avoid damage to the tea due to excessive temperature.
[0049] When the heating resistance wire 302 is energized, it heats the surrounding area. The blower 303 blows hot air around the heating resistance wire 302. The hot air moves upward through the ventilation plate 101 and through the ventilation holes on the surface of the arc-shaped ventilation cylinder 6 to heat, bake, and dry the tea leaves. The motor 401 drives the half gear 404 to rotate. The rotation of the half gear 404 meshes with the second toothed plates 407 on both sides, causing the U-shaped slide plate 405 to move back and forth on the surface of the U-shaped slide column 402. This causes the multiple driven gears 408, which are meshed with the first toothed plate 406, to rotate synchronously. The rotation of the driven gears 408 drives the transmission rod 403 to rotate back and forth in an arc shape, causing the multiple arc-shaped ventilation cylinders 6 to shake. This causes the tea leaves inside the arc-shaped ventilation cylinders 6 to tumble and roll back and forth. The hot air moves upward through the surface of the arc-shaped ventilation cylinders 6 to contact and dry the rolling tea leaves, making the tea leaves heat more evenly and improving the baking effect.
[0050] The rising residual heat will accumulate at the top of the inner cavity of the baking oven 1 and gradually be discharged through the pressure relief hole. At this time, due to the operation of the exhaust fan 701, some of the residual heat is extracted by the exhaust fan 701 through the trapezoidal cover 701 and sent back to the bottom of the inner cavity of the baking oven 1 through the air supply cover 703, and then moves upward again to bake and dry the tea inside the arc-shaped ventilation duct 6, further improving the drying effect of the tea. The residual heat extraction component 7 facilitates the extraction and reuse of most of the discharged residual heat, reducing heat loss and energy consumption.
[0051] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
